SPECIFICATION forming part of Letters Patent No. 536,333,, dated March 26, 1895. Application filed May 7,1894. serial No. 510.254. (No model.

To all whom it may concern: 7

Be it known that I, DANIEL H. GAIL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Swinging Window-Sashes, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to swinging window sashes, and its object is to provide a window sash that may be opened by swinging the same about its lower edge, and that may be readily removed completely from the window.

It has been customary heretofore to arrange the window sash in two sections adapted to be opened by sliding the same vertically, and my invention herein consists in so mounting the sashes that they may be opened by swinging, the same about the lower edge, the air entering the room through the opening formed by the partial opening of the sash, being directed upward by the oblique surface of the sash and a draft prevented.

I am aware that it has been proposed, heretofore, to mount windowshades and blinds so that they may be swung about a horizontal edge, but I believe myself to be the first to mount the sash in the manner herein described, whereby are accomplished the useful purposes set forth.

My invention will be readily-understood by reference to the accompanying drawings, in which Figure 1 is an elevation of a window embodying my invention. Fig. 2 is a sectional view thereof showing the sashes opened. Fig. 3 is a detail of the hinge plates. Fig. 4 is a View on line 4-4:, Fig. 1, of the device that holds the upper sash in its adjusted position. Fig. 5 is a front view thereof, the rod being shownin section. Fig. 6 is a view of a form of device for holding the sash in an adjusted position.

Like letters refer to like parts in the several figures.

The sashes are mounted to rotate about their lower edges, plates at a being provided thereon and carrying projecting pins a 0. adapted to engage suitable bearings or openings provided in plates b b secured to the window frame. The plates 6 are provided with vertical slots 1) enlarged into a rounded portion at the bottom, in which rounded portion the pins 0. are adapted to normally rest. As shown more clearly in Fig. 3 the pin a, shown in section and in that position which it would occupy when the sash is turned through ninety degrees, is cut away at one side so that when in this position itmay be raised through the slot b, the sash turning about the opposite edge. The sash may in this manner be re moved completely from the frame, but only when the pin occupies the position shown, for otherwise the pin will not pass through the slot b. The slot instead of being vertical may be horizontal or occupy any other position, the pin being cut away to fit the same.

The upper sash is shown provided with a longitudinally movable rod 0 which normally rests by its end within a hole or socket provided in the window frame'to maintain the window closed. A series of such sockets d d may be provided, into any one of which the rod may be inserted to maintain the sash in a more or less opened position. The rod is provided with an oblique end which causes theoutward movement of the rod when the window is moved to close the same, thus rendering it unnecessary to grasp the rod when it is desired to close the window. The rod may be normally pressed toward the frame by means of a spring d set into the sash. The outer end of the rod is provided with plane surfaces adapted to fit the opening 6' in the'plate e secured to the sash to prevent the axial rotation 'of the rod.

Fig. 6 illustrates an attachment that may be applied to the above form of adjusting device whereby the sash may be opened to a greater extent and maintained in its adjusted posi tion. A platefis pivoted to the frame atf provided with a slot f in which a headed pin or screw f provided upon the sash is adapted to move as the sash is swung. The end of the slot is enlarged at f so that when the sash is opened until the headed pin reaches the enlarged portion. the head of said pin may be slipped through the slot and the platef thus disengaged from the sash, thus permitting the complete opening of the same. The plate f is provided with a slot f through which the end of the rod 0 extends while it is in position to engage any of the holes or sockets d d in the window frame. In line with this slot are provided a number of hole's'j f into one of which the rod 0 may pass when the sash has been swung to such an extent that the rod 0 can no longer engage one of the holes at in the frame. In Fig. 6 the rod 0 is shown resting in the last hole, f, the sash being opened to its extreme adjustable position. If the rod 0 be withdrawn from the hole f and the sash swung until pin f reaches the enlarged portion f of slot f the plate f may be disengaged from the sash, and the latter swung completely open, as shown in Fig. 2.-

The window sashes when closed rest against the strips Z bounding the frame, which may preferably be faced with rubber to prevent the entrance of air between the frame and sash, and to afiord a tight fit when the sash is closed to prevent shaking of the sashes, an occurrence which renders the present sliding sashes objectionable. The rubber facing instead of being placed upon the strips Z may, of course, be provided upon the sashes. The sashes, as thus mounted, present many points of advantage over the present vertically sliding sashes which cannot be made to tightly fit the frame without calling for increased exertion in opening and closing them. Fur thermore, the window, when opened for the purpose of ventilation, permits the formation of a draft, whereas the sash of my invention, when opened for the purpose of ventilation, is swung about its lower'edge, thus presenting an oblique surface to the entering air which directs the same upward, thus preventing a draft. Again, in cleaning the window the sashes may be swung into the room, as shown in Fig. 2, thus bringing the outer faces of the panes within the room.

It is evident that myinvention maybe embodied in other forms, and I do not, therefore, limit myself to details, but

' Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with the window sash provided at the lower end with horizontal pins, of sockets provided in the frame adapted to receive said pins, and slots of less width than said sockets extending therefrom, said pins being cut away upon one side; whereby the sash may be removed from the frame, substantially as described.

2. The combination with a window sash adapted to swing about the lower edge, of a plate pivoted to the window frame and provided with aslot in which a pin provided upon the sash is adapted to move, a series of holes in said plate, and a rod carried upon the sash adapted to be inserted into any one of said holes, substantially as described.

3. The combination with a window sash adapted to swing about the lower edge, of a longitudinally movable rod carried thereon, a series of sockets provided upon the windowframe and arranged concentric with the pivotal axis of said sash, a plate pivoted to the frame, and provided with a slot in which a pin carried upon the sash is adapted to move, said plate being provided with a series of holes into which said longitudinally movable rod may beinserted, and with a slot through which said rod may move while in position to engage one of said concentrically arranged sockets, substantially as described.

In witness whereof I hereunto subscribe my name this 2d day of May, A. D. 1894.

DANIEL H. .GAIL.
